Struct phron_finality::sync::data::VersionWrapper

pub struct VersionWrapper<B, J, N>
where
    N: GossipNetwork<VersionedNetworkData<B, J>>,
    J: Justification,
    B: Block<UnverifiedHeader = <<J as Justification>::Header as Header>::Unverified>,
{
    inner: N,
    _phantom: PhantomData<(B, J)>,
}

Wrap around a network to avoid thinking about versioning.

Fields

inner: N

_phantom: PhantomData<(B, J)>

Implementations

impl<B, J, N> VersionWrapper<B, J, N>

where N: GossipNetwork<VersionedNetworkData<B, J>>, J: Justification, B: Block<UnverifiedHeader = <<J as Justification>::Header as Header>::Unverified>,

Trait Implementations

impl<B, J, N> Network<NetworkData<B, J>> for VersionWrapper<B, J, N>

fn next<'life0, 'async_trait>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = Result<(NetworkData<B, J>, Self::PeerId), Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Retrieves next message from the network.

Cancel safety

This method is cancellation safe.

type Error = <N as Network<VersionedNetworkData<B, J>>>::Error

type PeerId = <N as Network<VersionedNetworkData<B, J>>>::PeerId

fn send_to( &mut self, data: NetworkData<B, J>, peer_id: Self::PeerId ) -> Result<(), Self::Error>

Attempt to send data to a peer. Might silently fail if we are not connected to them.

fn send_to_random( &mut self, data: NetworkData<B, J>, peer_ids: HashSet<Self::PeerId> ) -> Result<(), Self::Error>

Send data to a random peer, preferably from a list. It should send the data to a randomly chosen peer from the provided list, but if it cannot (e.g. because it’s not connected) it will send to a random available peer. No guarantees any peer gets it even if no errors are returned, retry appropriately.

fn broadcast(&mut self, data: NetworkData<B, J>) -> Result<(), Self::Error>

Broadcast data to all directly connected peers. Network-wide broadcasts have to be implemented on top of this abstraction. Note that there might be no currently connected peers, so there are no guarantees any single call sends anything even if no errors are returned, retry appropriately.
